I have to say that I do not remember seeing in this discussion that in the
context of FrameMaker MIF stands for Maker Interchange Format (i.e. Maker, not
Model).
When I used FrameMaker (last time was with 7.2) I used MIF to clean FM files,
and also for FUN! For example, by editing MIF files (which are/were pure ascii
text) in MSWord (Yes I did), I could cause formatting changes that could not be
done through the FM menus (and were likely not supported).
